To all whom it may concern:

Be it known that I, EDWARD N. GApnnow, a citizen of the United States,residing in Newark, in the county of Essex and State Of New J r ey, havi v ed cer ain n w and useful Improvements in Machines for akingBrushes, of which the follo i g is a pecific t n.

My invention relates to machines for making rotary brushes havingskeleton: frames with bent-over prongs.

The object of the invention is to provide a machine of this kind formaking such brushes in a-quiek and f cien manner and for doing away wi hhe hhew su mg ma h n s and expensive hand e brushes men1bers, wherebythe rings whi h are clamped by the prongs and form part of thebrush-body are properly positioned for beiug s amp 'In the accompanyingdrawings, Figure 1 shows it front elevation of my improved machine,before operation, Fig. 2 is a front elevation of the machine at a pointin the op.- eration, Fig. 3 is a front elevation at the coin.- pletionof operation, Fig, 4 is a front view with parts in vertical section, ofa part of the structure shown in Fig. 1, .on a larger scale, and showinga bl noh of bristles and a skeleton frame in position ready for beingoperated upon, Fig. .5 shows in side View a bundle of bristles as itappears in the skelet n-f ame before bei g app ied to the machine, Fig.6 is a front view, .on the same scale as Fig, 4, and with parts invertical section, with the bristles spread from their original positionand in process of being sp ead pr paratory t clamping, an F g- 7 1s avertical section on a still larger scale of he die n elat d par s inPosition afte th lamping ope ation h been ompl ted- Similar letters ofreference indicate corresponding parts.

Referring to the drawings, the bed 10 is provided with Standards 11secured to a base-plate 12, which standards are provided with anintermediate plate 13 and a topplate 14. One of the standards 11supports a guideswheel 15 over which a rope 16 passes,

which rope has its lower end secured to a rod 17 connected with afoot-treadle 18 secured to the floor 19. The top-plate 14 guides a red20 which is secured at its upper end to a cable 21 passing over asuitablysup oited guide-rol er 22 and a s ond r l 23 and supporting aweight 24 which serves to balance the weight of the tube 26 and at:tached parts. The rod 20 is connected with a second rod or tube 25 whichis eonnected with a tube 26 guided in the plate 13 and carrying at itslower end a die 27. The plate 14 supports by means of a suitable bracketbearing an elbow-lever 80 which has its free end connected with a cord81 having secured thereto a handle 82. To the elbow lever is pivoted at29 a link 30 which is also pivoted to the tube 2.6 at .31, above the pte 3.- The upp r end of the rope 16 is attached to the elbow lever at.33. The lever and link form a tQggle-joint, which is operated bydepressing the footre d e 1. which draws the ope 1.6 d w wardly andthereby gives the elbow lever 80 an inward movement. The link 3.0 isthereby moved and resses the sleeve 26 downwardly, the par 5 taking theposition shown in Fig, 2. A. further operation is obtained by pullingthe handle .82 until they take the po t n sh n in Fig. 3.

hlovable within the tube 26 is a hollow plunger-sleeve which has itslower end L evele a d i uppe nd o ed by a blo k 37 to which is secured aplunger rod 38 havre a nut 3 a it pp r en bey nd a t n verse artition 40secured in the tube and th g which th pl ng rod s r o move, Between thepart tion and the block 37 a compression spring 41 is interposed. Thisarrangement 'of parts permits the movement of sleeve 26 and die and thesleeve 35 relatively to each other.

Within th sle 5 is e pl nge 2 h vng a ee tral b and a onic lo er end,and a pin p oieshe later l y hrough a longitudinal slot 34. Xcompression spr ng 43 etween the 991 3 an h p unger 1,1

base-plate, and said sleeve supports at its,

upper end a die 52, which registers with and corresponds in diameter andshape substantially with the die 27. Movable within the sleeve 50 anddie 52 is a plunger-sleeve 53, which is provided with a beveled upperend and which is secured at its lower end to a block 54. A rod 55 isalso secured to the block 54 and passes loosely through a block 56 atthe lower end of a tube 58 secured to the sleeve 50. A nut 57 is screwedon the outer end of the rod 55, and a compression spring 83 isinterposed between the blocks 54 and 56. A rod 59 is also secured to theblock 54 and extends upwardly within the sleeve and a compression spring61 interposed between the block 54 and a plunger 62 in the sleeve. Theplunger 62 has a central bore adapted to receive the rod 59, on which issupported in the bore a center-pin 63, which is removable from andextends upwardly beyond the upper conical end of the plunger 62, asshown in Fig. 1. The 0 plunger has a laterally-extending pin 64 movablein a longitudinal slot 65 of the sleeve 53. The bore of the upperplunger 28 is adapted to receive the center-pin 63, when the plungersand connected parts are brought together. The strength of the varioussprings is so proportioned that when the parts are broughttogether, theplungers first equally yield, then the sleeves equally yield and retreatwith the plungers, and-the dies are thereby exposed for coiiperation.

The operation of the machine is as follows: A ring 68, which is to formpart of the completed brush, is placed around the sleeve 53, and restsupon the die 52. A similar ring is frictionally held in position on thesleeve 35 at any point below the die 27. A bundle of bristles 70surround ed by a skeleton-frame 71 having bent-over prongs 72 as shownin Fig. 5, and having the bristles evenly divided relatively to thecentral axis and held in position by means of an internal mandrel 66 isplaced on the pin 63 by having the pin enter the central bore of themandrel. The parts then have the position substantially as shown in Fig.4. Thereupon the lever 80 is operated by means of the foot-treadle 18.This causes the plunger 28, sleeve 35, die 27, and attached parts, todescend. The plunger 28 meets the mandrel 66 and presses thereon,

causing both plungers 28 and 62 to slide inwardly in their sleeves.During this approach of the upper plunger to the mandrel, the conicalend of the same and the beveled end of the upper sleeve have entered theupper portion of the bristle-bunch and have by their conical and beveledportions spread outwardly any inwardly-projecting stray bristles, whichwould otherwise be caught by the parts and eventually crushed by thedies. The plungers yield and retreat until the ends of theplunger-sleeves are flush with the same, or nearly so, and during thisapproach of the sleeves the annulus of bristles has been spreaduniformly, and wide enough so that the rings 68 and 69 and dies 27 and52 will not catch the outer ends of the bristles when these partsfurther descend;- The movement of the sleeves toward each othercontinues until the bristles, being bent, ofi'er sufficient resistanceto prevent further advance of the same, in which position t-hey'aresubstantially horizontal, and are thereby divided by the upwardlyand'downwa'rdly projecting prongs 72 of the skeleton-frame intoseparate, oppositely arranged or staggered tufts extending radiallybetween the prongs. In this position they are held by the sleeves duringthe further descent of the die 27, which now takes place. Said dieapproaches the lower die 52, and by means of the upwardly and downwardlyextending annular grooves respectively 90 and 91 of the dies 27 and 52,the prongs 72 at each side 'of'the skeletonframe 71 are turned back andupset upon the rings, in the position shown in Fig. 7, thereby clampingthe bristles in place and all the parts of the brush together as shown.The final clamping action is effectively accomplished by a downward pullon the handle 82. After the compressing of the parts has been completed,the handle 82 is released and the levers take their original position asshown in Fig. .1, the die 27 and sleeve 35 ascendin under the influenceof the weight 24, whlle at the'same time the lower plunger 62 and sleeve53 also ascend, leaving the mandrel 66 on the pin 63 and the formedbrush surrounding these parts. The mandrel and brush may be removed, andthe machine is then in condition to receive another bunch of bristlesfor repeating the operation.

The machine describe-d provides means whereby brushes may be made in avery quick manner and thereby saves considerable time in the process ofmaking the same. Furthermore, the machine produces a brush that hasequally distributed bristles, and is efficient in manufacture.

It is obvious that changes may be made in the construction withoutdeparting from the spirit of the invention, as set forth in the claims.

I claim:
